or containers of this class which are utilized in the evaporation and. condensation of milk and other fluids.

The principal objects of my invention are to so arrange and dispose the heating el ements, within the tank, that the smaller will project within the larger and will be properly located within the converging walls of the lower part of the tank, to so connect the heating elements that the heating agent will circulate from one to the other and to provide a simple, efi'icient and durable device of this class.

With the above and other objects in view, this invention consists in the construction, combination, and arrangement of parts as hereinafter fully described and claimed and as shown, in the "iccompanying drawings in which a preferre'd embodiment and adaptation thereof is illustrated.

In the drawings, Figure 1 represents a side view of my improved tank or container, partly in side elevation and partly in vertical section to show.the interior construction; Fig. 2 represents a transverse horizontal section through the improved tank or container on line 2+2, Fig. 1, looking down. wardly or in the direction of the arrows in said Fig. 1; and Fig. 3 represents a transverse horiz'ontal section through the i111 proved tank or container on line 3-3, Fig, 1, looking downward or in the direction of the arrows in said. Fig. 1.

In the following detailed description of the preferred embodiment or adaptation of my invention, like letters, characters, and

symbols refer to and indicate similar parts and elements in the accompanying drawings.

The preferred embodiment of my improved tank or container as illustrated, comprises a body which is constructed in a plurality of parts or members suitably joined or bolted to each other.

Referring to Fig. 1, it will be noted that consists of an intermediate cylindrical member 1, a rounded lower terminal member 2,

and a rounded and reduced upper terminal member 3 to which a suction pipe l is suit ably fastened by bolts 5 or the like.

The members or parts are detachably fastcned to each other by bolts 6 which are fitted through the contacting outwardly-en tending horizontal annular flanges 7 formed on the abutting edges or ends of the members as shown in Fig.- l.

The heating elements are arranged within the tank or container and in their preferable form, as shown, comprise an upper hollow walled annular element 8, which is rigidly supported within the intermediate memher and concentric with said member a series of equidistant pipes or tubes 9 extending from the wall of said element to.

and through the circular wall of the intermediate member, being firmly clamped thereto as shown at 10 in Fig. 1, and a lower hollow walled annular element 11 concentric with the upper annular element but of considerably smaller circumference than said upper annular element disposed principally within the lower rounded. member 2 and having its upper portion projecting slightly within the upper annular member as shown in Fig. 1.

The lower annular element 11 is supported from th rounded member 2 by a series.

of depending tubes or pipes 12, which extend from the lower edge of the element 11 down to and through the wall themember 2, and is additionally supported at its top from the intermediate cylindrical member by one or more horizontal tubes or pipes 13.

Both the upper element 8 and. the lower element 11, though they diii'er in size, are of similar construction, each having annular concentric walls which extend fairly'close to each other and are joined together at the upper and lower edges to a narrow annular. closed space for the heating fluid indicated by llin the upper element and 15 in the lower element in Fig. 1. To increase the heating area oi-the elements, both the -in her and outer walls thereof are provided with a series of corresponding horizontal corrugations, substantially as shown at 16 in the upper element'and 17 in the lower element.

The steam or other heating fluid is conducted to the upper element through one or more oi the pipes or tubes 9 which are suitably connected. to a source oi supply (not
